Please explain

I know that light lines on the opk are negatives but could it help you predict when your positive will come or is that not how it works? Could you tell me what the lines looked like for u a few days before and a few days after a positive opk

Re: Please explain

For some people yes it will help you gauge when it will be positive.. for me it goes from negative to positive very quickly.

Re: Please explain

everyone is different, but when i used them this month, the lines got darker the closer i got to o'ing. you could def tell the difference though when you get the surge...its as dark as the control line if not darker.

Re: Please explain

i would think if u r getting ight lines that continue to get darker a surge is coming..

unless u caught the end of the surge in case the next day there would be no line

hth!
